Under President Barack Obama, the United States military suffered greatly. Budget cuts damaged its readiness, and a lack of concern on the part of the Obama administration led to some serious problems at military bases — problems that could have cost thousands of lives.

According to the Army Times, a report released in June by the U.S. Department of Defense Inspector General highlighted some of the serious consequences of a lack of funding and overall negligence that was common during the Obama administration.

The report states that in 2016, it was discovered that 1.5 milliliters of sarin gas was missing from the U.S. Army Dugway Proving Ground in Utah (mostly referred to simply as “Dugway.”)

While 1.5 milliliters may not sound like much, the material is so deadly that a single drop the size of the head of a pin is enough to kill an adult human, according to the National Interest — and the army never even knew it was missing.

“Furthermore, Dugway officials did not immediately notify the chemical materials accountability officer of a 1.5-milliliter shortage of the chemical surety material sarin (GB) identified during an April 19, 2016, inventory nor did they properly document the results of that inventory,” read the summary of conclusions of the report.

The report stresses that the missing sarin most likely leaked out, or simply evaporated, due to the use of containers that were as secure as they needed to be for such a chemical.
